Fixes #148

Added /dist and extension.d.ts specifically as they were mentioned in the Issue

hi @Anshuman-37, thanks for the PR!

Each template has its own .gitignore already. Can you pick one for reference and push a commit adding all its lines along with the lines you are adding? This way we streamline the process.

Also please add a console.log message to inform users about the operation, thought of something like:

export function writingGitIgnore() {
  return `🙈 - Writing ${brightYellow(`.gitignore`)} lines...`
}

Let me know if you need a hand btw, happy to assist

Should the original gitignore's be deleted too?
